The 5 members of B2ST recently left Cube Entertainment to build their own independent label Around US Entertainment. Unfortunately, they're unable to promote with their group name because B2ST is registered as a trademark by Cube. As a result, Doojoon, Kikwang, Junhyung, Dongwoon, and Yoseob can no longer officially call themselves B2ST.

When Doojoon guested on the February 13 broadcast of 'Please Take Care of My Refrigerator', MC Kim Sung Joo introduced him with the words, "He was called eun-dong-dol (exercise idol) for being athletic, mukbang-dol for his great appetite, and namchin-dol (boyfriend idol) for being handsome. He is now self-called sportsman Yoon Doojoon." 

Doojoon, who is well known to be an athlete with a great love for soccer, then introduced himself, saying, "Hello, this is sportsman Yoon Doojoon."
